Many of you may be considering using small VGA displays for your cockpits,
especially the F16 and F/A-18 crowd. DO NOT ASSUME ANYTHING with these
commercial displays.
The rest of the world considers that when a connector has a keyway, it's
there to indicate pin 1. Well in the display industry, when you have a 10
pin keyed card edge connector, the keyway indicates *pin 10*. I got
lucky, putting 12VDC into the lower leg of the brightness pot shouldn't
have killed the CRT[1]. Save yourself the stress and VERIFY connector
orientation. I could have easily killed some very spendy CRTs.
Be *careful!*

[1]According to the engineer at Omni Vision (the mfr), putting 12V to the
board like I did shouldn't have hurt it. We'll see.
